IPC: C21D1/767
Filed: 1983-09-09
Abstract: PURPOSE:To increase the pressure in a cooling chamber and to use effectively the recovered gas for purging to the other furnace by introducing a liquefied gas into the chamber to increase the cooling rate when the cooling rate by the cooling gas under circulation decreases down to a prescribed rate or below and recovering the liquefied gas to the outside of the chamber. CONSTITUTION:The cooling gas such as gaseous N2 purged into a cooling chamber with a two-chamber box type annealing furnace is passed through a coil X to cool the coil and is thereafter led through a plenum chamber 2 to the outside of the cooling chamber. The gas is again introduced 5 into the cooling chamber after cooling 4. When the cooling rate of the coil X decreases down to a prescribed rate or below, liquid N2 12 is injected 10 into the cooling chamber to cool the coil X. The N2 evaporated by such injection increases the pressure in the cooling chamber by expanding in volume and therefore a part of the gaseous N2 is recovered to the outside of the chamber and the pressure in the chamber is maintained under a specified pressure. The recovered gaseous N2 is stored in a storage tank 16, etc. and is used for purging to the other cooling chamber which is emptied upon ending of cooling.

Title: Stripper device of punching die and punch assembly body using the same
Inventor: FUJITA SATONARI
IPC: B21D45/00
Filed: 1994-07-18
Abstract: PURPOSE:To prevent the rapid change of a spring constant even if a blank thickness is changed and to improve the durability by generating a reaction force on a piston confined inside a cylinder in the case that a punch head is pressed by a punching element of a punch press. CONSTITUTION:A sealed gas 7 having an adequate pressure is sealed in a gas filling room 51 to obtain a required reaction force (load). In this case, a high pressure gaseous nitrogen 7 is sealed, and the max. reaction force of about 3000kg is obtained. Increasing rate of load (spring constant) of a stripper device of this punching die is considerably small in comparison to a spring for a stripper of punch assembly body for a conventional punch press. This load increasing rate, that is, the spring constant can be changed arbitrarily by changing the volume of a cylinder 5 without changing the stroke amount and the maximum load in the case of the stripper device 3. Therefore, almost uniform stripping force can be obtained over the whole range of thickness from thin thickness to the maximum thickness to be worked.
